Abstract: Chinese Sturgeon Natural Reserve (CSNR) is a typical river ecosystem in the middle of the Yangtze River. An evaluation system of the river ecosystem services of CSNR was established using the so-called Market Price Approach, Expense Payment Method, Contingent Valuation Method , Substituted Value Method, Cost Analysis Method and Opportunity Cost Method. The results showed that the total values of the ecosystem goods and services of the natural reserve amount to an estimated 73.57 million USD. The use-values and non use-values were 72.5 and 27.5%, respectively. The direct use values, including fisheries, water supplies and others,reach a total of about 24.23 million USD; On the other hand, the indirect use values, which include endangered species,purification costs and degradation losses, have been estimated at cost levels of approximately 29.12 million USD, indicating with 39.6% its important role of the total value. Meanwhile the non-use values of CSNR in the Yichang Reaches of the Yangtze River were assessed by a contingent valuation method (CVM) and the willingness to pay(WTP), The study shows that the annual non-use values of CSNR is up to 20.22 million USD, of which its existence values is in the range of 8.59 million USD, its bequest values 8.03 million USD, and the option values around 3.6 million USD.
